The brain is an amazing thing.

It can do millions of calculations and think a thousand thoughts.

But it can be fooled and here's the proof!
One way of fooling your brain is to put your hand-eye co-ordination to the test.

This is the same ability we use to catch a ball, or even just to put food into outr mouths.
Fearne drew this star using her right hand. But the hand was hidden underneath a block, and her left hand was behind her back so that she couldn't use it as a reference.
All she can do is look in a mirror, at the reflection of the star.
Fearne found it very difficult because all the information her brain was receiving is back to front.

If she moved her hand forward, it went backwards, and vice versa.
The usual hand-eye co-ordination that would normally be used for this activity was prevented - confusing the brain!
And check out these cards.

They've been ordered one behind the other...
..as have these.

So why do they look so odd?
Well, when an object like the pink card looks like it's in front, the brain assumes that it's closest.

But as you can see, it's clearly not.
Moving the camera reveals the illusion. Good, isn't it?

Seeing isn't always believing!
